Anyone familiar with TCI handheld controllers for auto?

And I guess that only a jumper wire is necessary for the clutch pedal Cruise kill switch?

No, but I think I might need to go to 3.23, or 2.73, with the new OD @ .67, instead of .5 of ZF 6th. Shift light shows up near 70mph...

Yes, purple for some reason comes to mind.

Clutch also had a vacuum port make.
Good luck.

You don't need to be concerned with the "shift light" that's ECM controlled and is still looking at the information that's there. I would think the 3.45 maybe a good choice. The next available gear for the D44HD would be a 3.07 but I believe you've got lots to occupy your time with out worrying about the gear.

I don't recall converter choice either but the more involved the "sorting out" becomes it seems it wasn't thought out particularly well from the start. Hate to say that but it's becoming quite evident!

I believe if I were in the situation and had something else to drive I'd "lawyer up" with your documentation and performance trail of the shop and attempt a recovery of all "labor charges" or a court ordered commitment that they'd be responsible for funds required to correct the install. You're in the same state as the shop which is a plus I'd think but I'd chase the money maybe first. If I could get on a court docket soon I believe it's something I would consider - I'm guessing you know a couple!

Since this is a 4l60e, the OD ratio will be 0.70:1, just like the other 700r4,4l60, 4l60e, 4l65e,4l70e's.
4l80e= 0.75:1
The only GM 4 speed auto to run a 0.67:1 OD is the 200R4 trans. IMO The 200r4 has teh best ratios for acceleration AND low cruise rpm. I prefer the higher 1st gear of the 200 as there is less rpm drop upon upshift into 2nd. Quite often the large ratio difference of the 60e family pulls revs down out of teh powerband, esp with stock stall torque converters. The newer 6l80e/90e transmissions are even worse for rpm drop during upshifts than the 4l60e family.

The 2.74:1 1st gear, 1.57:1 2nd 1:1 4rd and 0.67:1 OD
4l60e
3.06:1 1st, 1.62:1 2nd, 1:1 3rd and 0.70:1 OD

4l80e
2.48:1 1st, 1.48:1 2nd, 1:1 3rd, 0.75:1 OD

6l80e/90e
1st=4.03:1 2nd=2.36:1 3rd=1.53:1 4th=1:1 5th=0.85:1 6th=0.67:1

Swapping from a 4l60e/700r4 to a th-350 is good for 3-4 tenths alone.

I tied in a ground there GC, and clipped to the seat anchor bolt with alligator clips.

Went for a spin, and as usual, after about 5 minutes (Closed Loop, with an energized circuit causing interference???), at a stop, it went to 43, 30, 100 even... UGH. Was kind of hopin' you were right... but.



MAN!!! WHAT COULD CAUSE SPEEDO READ, WHILE SITTING STILL???

Well, let's read some more here:



Well, let's see how close they are...:

White Input, and Brown Output



Hmm... over there on the right, looks like the White Input, and the Brown Output are taped together pretty tight.

I wonder if that's routed too close???

[Schrade]

I cut the tape, and separated the leads.

Took a ride, and NO DIFFERENCE.





So from the DD Troubleshoot list, that leaves tach interference. But the original VSS harness Purple + Yellow is in place, so tach interference isn't likely...

#2 switch is already on 'ON', for sensitivity adjustment.

That leaves swap to Purple, from Yellow.

Right???

Or a broken DD.

I could cut the DD out of the speedo loop, and try the Orange speedo output, DIRECTLY form the Tranny Control Module, to the Yellow VSS lead, but the Comm Error of the handheld prevents writing the Pulse Per Minute setting to the Module... WAH.

Where is the sensor ground wire? Its one of the two pins from the VSS sensor in the trans.

Page 8 of the .pdf http://www.dakotadigital.com/pdf/sgi-5.pdf

"Speedometer will read Tach wire too close to Route the speed signal and tachometer
when the vehicle is speed signal wire. wires away from each other to avoid
sitting still. interference.

Signal In and OUT wires Route the input and output wires away
routed too close. from each other to avoid feedback.

Ground interference. Make sure the speed sensor and SGI-5

are grounded together."

Hey there Dominic...

I just wired in a ground for the sensor, as GC was trying to point out. The pics I used in the latest posts are earlier, and don't show the new ground for Sensor...

I got the .PDF (thanks Dave H), and I think you've posted the same excerpt, that's the same pg. 8 as above.

What lead [or terminal] is for the speed sensor ground, to join to the DD/SGI ground connection???





OR SHOULD I JUST LOOP MY NEW DEDICATED 'SENSOR GROUND' LEAD, BACK INSTEAD TO THE 'GROUND' CONNECTOR???

Why aren't the internally bridged???

[XfireZ51]

BTW, Your output is hooked up to OUT 3, looks like it should be coming from OUT 4 based on the .pdf

OUT3, 8000ppm AC: most aftermarket speedometers and cruise controls
OUT4, 4000ppm oc: most TPI computers and some OEM cruise controls

OUT5, 2000ppm oc: most TBI computers and some OEM cruise controls
